For copper, digital zero is <300mV, digital one is >3.8V. That means anything below 300mV is ignored. Plugging into an unused switch port is ignored because the switch is 1) ignoring a passive component component. 2) Because a switch only allows one port to port connection at a time. This isn't up for discussion. This is just basic Ethernet operations. When you bounce any Ethernet tweaks or cables against reality, there's nothing there.
Has anyone tried the new Synergistic Research UEF Performance Enhancer - Ethernet Filter?
I was wondering if anyone has tried the new (and expensive) Synergistic Research UEF Performance Enhancer - Ethernet Filter. I find that some SR products such as their cable line are nicely effective while others..........well, maybe no so much. According to SR these things run $300 each and plug into unused ethernet ports to "filter" ethernet signals. Please weigh in here so I can ascertain whether they are worth a try. Thank you.
